Answer:
Atomic number of the daughter isotope = (Atomic number of the parent isotope) - 4
Explanation:
An alpha particle has atomic number of 2 and a mass number of 4
Losing two alpha particles would lead to a reduction of 4 in atomic number and 8 in mass number for the radioactive isotope, to give the stable daughter isotope.
Answer:
A. Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity on the object.
Explanation:
Mass is also a scalar quantity associated with the amount of atoms and/or molecules that constitutes the object. While weight is a force due to the action of gravity (either on our planet or any other one) and therefore a vector quantity that we routinely use as scalar due to the fact that it is always pointing down (towards the center of the Earth) so we ignore a bit the direction associated with it.

A) It would likely contain all the isotopes of nickel shown in the chart in the same proportions.
[only one answer here, everything is wrong other than this ]
Hope this helps!
The term precision is how repeatable the experiment is
Accuracy is how close to the right answer you are.
